Figure 1-1 provides a flow chart of the Oracle Portal, Forms, Reports, and Discoverer upgrade process. Review this chart to get familiar with the steps you will be required to take, based on your existing Oracle Application Server environment.

With the introduction of Oracle WebLogic Server, the topologies for Oracle Portal, Forms, Reports, and Discoverer have changed somewhat. Before you begin an upgrade, make sure you are familiar with the basic topologies in Oracle Fusion Middleware 11g.

The Oracle Discoverer and Oracle Portal components require schemas that must be installed in a database. Before you can install or upgrade the schemas, you must make sure the database is a supported version.
